1.5.3 Cage Clamp terminals
The Cage Clamp

terminal system is now available for circuit breakers, con-
tactors, overload relays, and time relays.
Cage-type clamping units, known as Cage Clamp terminals in the case of
SIRIUS products, facilitate quick and maintenance-free wiring.
Design
The Cage Clamp terminal consists of two parts:
• A power rail for conducting current
• A sprung cage-type clamp for clamping strength

Conductors
The Cage Clamp terminal on the switching devices clamps all copper wires
(single-core, stranded and finely stranded) from 0.25 mm
2
to 2.5 mm

. The
conductors can be clamped directly or with some protection for splicing. To
this end, wire end ferrules or pin-end connectors can be placed on the con-
ductor ends. The best solution is an ultrasonically condensed conductor.
